Tim Lambert provides the abstract of Zhen-Shan and Xian; MW was kind enough to send the text. I’ve seen it before… probably via Monckton or one of the std.septic channels. Lambert describes it as “just a rubbish paper that should not have been published”. It comes up as one of the Schultz 7.

But why is it rubbish? (of course it must be, since it rejects the consensus :-), but is more detail of any value?).

Well, lets start off with the nearly-ad-homs: the English is in places terrible, although better than my Chinese. In most cases, this isn’t a fair accusation to level at authors, since it has no real bearing on their ability as scientists, but its an indication that the journal standards may be rather low (the full ref is: Meteorol Atmos Phys 95, 115-121 (2007), DOI 10.1007/s00703-006-0199-2; I’m not familiar with the journal; its a minor one). But sometimes its so bad that the sense disappears: what does It appears to agree with the above conclusion: temperature in China has been falling on century scale in the next 20 years. mean? Should “has” mean “will”? Or should “next” be “last”? Or their conclusion: We consider that CO2 greenhouse effect impact on the trend of global temperature, simultaneity we expect to find the effect on climate change on different timescales by analysis the solar activity, earth movement (nutation, rift and volcano activity) and the others greenhouse gases using EMD method. I think that may be a suggestion for work they might do in the future, but its hard to tell.

But on to the paper. Its essentially a sexed-up Fourier analysis of the temperature record, and discovers, ta-da!, that the temperature doesn’t linearly follow CO2 (fans of radiative physics will know that they ought to be looking for linearity in log(CO2). Although that wouldn’t make a big difference, the fact that the authors don’t even seem to realise this gives you some idea of where they aren’t coming from). This allows them a major conclusion: The global climate warming is not solely affected by the CO2 greenhouse effect. Wow. Really? I think we knew that already (see? the paper *does* support the consensus…). Essentially, this is yet another “there was a period of cooling from 40-70 but CO2 was going up then so it can’t be CO2″, which has been done to death recently (aerosols). Or as the authors say: The best example is temperature obviously cooling however atmospheric CO2 concentration is ascending from 1940s to 1970s. The authors don’t mention aerosol anywhere.

Other things are bad too: From Fig. 3, we see clearly that global and NH temperature will drop on century scale in the next 20 years is the sort of quote that makes them beloved of the septics. But fig 3 only goes up to 2000. You cannot see clearly from fig 3 what their “prediction” is.

So do they provide any predictions? Only very vague ones: on century-scale or 60-year scales, the global temperature tends to descend in the coming 20 years. They provide no graphs of any future “predicted” trends to back this up – all their graphs stop at 2000. Because the English is so poor, its really nto clear whether these trends are supposed to include extra CO2 forcing in the future or not: Therefore, if CO2 concentration remains constant at present, the CO2 greenhouse effect will be deficient in counterchecking the natural cooling of global climate in the following 20 years. suggests not.

Conclusion: Lambert is right: this is indeed “just a rubbish paper that should not have been published”.

    Didn’t Lubos mention this one when it first appeared? I remember viewing it and thinking that it was pretty meaingless and without much relevance to the physical world. I think I even read a quick two line review from yourself on it too.

    This goes into the same category as Chilingar and Khilyuk I’m afraid – the woefully bad category.

    I think we were all aware that such papers existed, and we knew all along how wretched they really were. Why would anyone hold this up and put their name to it and endorse it as good work? I’m quite happy for Monckton et al to put their names to this sort of thing, as I think TL has pointed out: this standard of paper actually discredits anyone who cites it.

    Dear Paul, thanks, yes, I did, but the posting about “peer-reviewed global cooling” was mostly composed of links.

    http://motls.blogspot.com/2007/01/peer-reviewed-global-cooling.html

    Most climate scientists, such as the owner of this blog, would transcend their limitations if they were able to publish a paper that uses Fourier analysis. Criticizing the English of Asian scientists is really the only thing that these angry dogs can do.

    [You clearly haven’t read my papers :-). And don’t you mean “running dogs of imperialism”? Meanwhile… your list of peer-reviewed cooling is deeply unimpressive, as is your failure to actually quote from any of them. I remain suspicious of simple titles, as cherry-picking and misunderstanding is all too easy.

    The Z-S and X paper is the only one I’ll give you for the moment, and… its rubbish. Though even their junk analysis manages to attribute 62% of NH temperature variance to CO2. As science. Do you… (a) think its good (b) think its bad (c) haven’t read it well enough to decide? Oh, and what do you think “temperature in China has been
    falling on century scale in the next 20 years.” means? -W]

  6. Hmm… yeah, this paper is horrible… but I’m interested in signal processing, so I decided to read up on this “empirical mode decomposition” stuff.

    And here’s my take on the Zhen-Shan and Xian paper and how they use the EMD: The empirical, the mode, and the decomposition. :)

    [Nice post. Thank you -W]

    I received 1 st mortgage loans when I was 25 and that aided my relatives very much. However, I need the short term loan once more time.

    I had got a desire to begin my firm, however I did not have got enough amount of money to do that. Thank heaven my close fellow proposed to use the loans. Thence I took the credit loan and made real my desire.

    I strictly recommend not to wait until you earn enough amount of cash to buy goods! You can just get the business loans or just student loan and feel free

    There are many choices available for accepting an education these days,you can buy term papers or buy research paper which is intereating news for those who have not yet compelled. truly, essays writing is not an easy product so try make right decision between composing on yor own or to buy essays about this topic. Maybe you need help with definite investigation , maybe you want help in producing a fresh intention on a topic that is vast and not an easy.
